Psectrocladius (Psectrocladius) schlienzi Wuelker 1956

Psectrocladius (Psectrocladius) schlienzi Wuelker, 1956 Material examined. 1 pupal exuvium, Lake Sinevir (L 1), 7 May 2018. Distribution. Palaearctic? In addition to some European countries (Austria, Denmark, Finland, Germany, Great Britain, Italy, Moldova, Netherlands, Norway, Portugal, Slovakia, Czech Republic, Spain, Sweden, Switzerland; Ashe and O’Connor 2012; Syrovátka and Langton 2015), it was also recorded in Mongolia (Hayford 2005). However, the species may have a Holarctic distribution, provided that its presence in North America can be confirmed (Sealock and Ferrington 2008). Baranov et al. (2024) found a species resembling P. schlienzi in Namibia, but it is possible that the specimen belongs to a yet undescribed species of Psectrocladius related to P. schlienzi. Habitat. Different types of stagnant waters from lakes to pools. For example, the only record from the Carpathians comes from a shallow pond in an exploited part of an alkaline fen (Bitušík and Illéšová 1998). Its occurrence in slowly flowing waters is exceptional (de Beauvesère-Storm and Tempelman 2009). Remarks. The records are scattered across Europe, and it seems that the species is not abundant anywhere (Moller Pillot 2013).
